If i remember correctly you can pass a txt file to pacman when installing packages, but i could be wrong. There is also BlendOS, which from what i can tell has an immutable base, with a toml config on top of it to install the additional packages you want. Never tried it myself though. I also use NixOS because i wanted to be able to reproduce my riced out system more easily if i have to reinstall. I do wish this space had some more competition, because it might make this way of running a distro more approachable. The closest thing i’ve seen aside from guix is probably those ublue customized images that you can build, but i’m not sure how comparable that is.

If you prefer stacking then maybe wayfire is worth taking a look at. It’s a stacking compositor but it has eyecandy as well.
